Abstract
The present invention provides a system and method for the diffusion of illumination from discrete light sources such that the illumination is blended and directed in one or more desired directions. The illumination system comprises a substrate having a plurality of light-emitting elements thereon which are arranged in an array, wherein these light-emitting elements produce illumination at one or more wavelengths. Proximate to the light-emitting elements is a diffuser, which collects the illumination produced by the discrete light-emitting elements and redirects this illumination in one or more predetermined directions, thereby blending together the one or more wavelengths of illumination and concentrating the illumination in the predetermined directions. The illumination system further comprises a power system, which provides energy to the light-emitting elements thereby resulting in their activation. Through the blending of the illumination produced by the discrete light-emitting elements together with the redirection of the illumination in a desired direction, both of which are enabled by the diffuser placed proximate to the discrete light-emitting elements, the creation of a blended pattern of illumination from these discrete light-emitting elements is provided, wherein this pattern of illumination can be one or more lines or planes of illumination.
